Some companies, like Adobe, charge an ongoing subscription fee that kills your software when you stop paying. There’s many different ways to buy and sell software, whether it’s a one-time license, shareware, free-to-play with in-app purchases, subscription, or just giving it away. And we can’t forget about those poor executives! After all, their private jets won’t fuel themselves, and that expensive C-check is coming up soon. Nobody likes doing it, but programmers gotta eat.
